Asymmetric encryption solves the problem of transmitting the password safely ("solve" is a rather optimistic word, maybe "delegates" is more appropriate); if you can safely transfer passwords from point to point, then using symmetric encryption is far easier.
- throwawayish 10y agoAsymmetric cryptography transforms key distribution problems into key management problems. Which is just a different problem, not necessarily an easier one, like you say.
- rakoo 10y ago> Asymmetric cryptography transforms key distribution problems into key management problems. That's a very nice way to put it, I'm going to reuse that !
- ausjke 10y agomore importantly, they're more cpu intensive and slow to deal with large files
- throwawayish 10y agoAsymmetric encryption adds constant overhead, independent of message size. Unless you're doing it wrong.
- ausjke 10y agowhile not an expert I disagree, encrypt a 1GB file must be different from 1MB file, no matter it is sym or asym encryption. normally Asym is for keys while symmetric encryption is for the real content.
